EYEGLASS GUARD AND FRAME.

SPECIFICATION forming part of Letters Application filed November 9, l 8 9 6 To aZZ whom it may concern:

Be it known that I, JAMES T. BRAYTON, a citizen of the United States, residing-at Ohicago, in the county of Cook and State of Illinois,have invented certain new and useful Imwhicli are fullyset forth in the following speci-. fication,referencebeing had to the accompanying drawings, forming a part hereof, and in which Figure 1 shows my said new eyeglass-guards in front/view with eyeglasses. Fig. 2. showsa transverse section of Fig 1 on the plane 2 2 of Fig. 1 looking inthe direction of the arrows. Fig. 3 shows the clasp d in perspective and on an enlarged scale. I

Like letters of reference denote like parts. The object of my invention is to improve the construction and operation of guards foreyeglasses, so that they may have a firmer hold andalso adapt themselves more readily to the varying forms of noses, and also to have be shaped to any desired special form.

To attain saiddesirable ends,I construct my; said guards in substantially the following mauner, namely a I place a revoluble shaf t dat right and hold 'it at one end in bearings 61 at the clasp or strap 61, heldbetween'the box sides a of an eyeglass-post b, .and let said shaft project a suitable distance beyond the lensplane. To the free end of said shaft are attached oppositely-projecting arms 6 of as great length as circumstances will permit for their best results. Said arms are preferably round in cross-section to allow of convenient shaping into desirable form and position. To the ends of said arms are attached disks or pads D, loose-jointed on pins e to permit said pads to touch all the surface they cover on account of said universal joints. Said clasp d is held on the posts and between the box sides a by means of a screw a,which also passes through the ends of the eyeglass-spring G, whereby the parts A B are connected. The shaft dis adjustable by means of the oblong holes g, of which there may be several in the clasp cl, whereby said guards become adjustable to the focal axis of the glasses. Owing to the great distance between said pads there is obtained great leverage at their hold, and through said universal adjustment of said pads the glasses are held firmly with far less Patent No. 648,585, dated May 1, 1900.

spring-pressure, and therefore less injury to the wearer from said guards. The pressure required for the ordinarily used guard is so great that it becomes exceedingly' uncomfortable, especially in hot weather, and such spots of contact very frequ'ently grow into sores, and'thus prevent the use of such glasses entirely. My improvement herein set forth greatly reduces. said.

troubles and inconveniences and holds the sition than the old forms can do.

What I claim isv 1. In eyeglasses, the combination with a rotatable shaft having opposed arms carrying pads at their outer ends, of a folded strap forming a shaft-bearing at the folding-place of said strap, for said'shaft, transverse to the lens-plane, substantially as specified.

2. In eyeglassesflhe combination with eyeglass-posts having box sides, of a doubled strap longitudinally adjustable in said bOX-' posts, a shaft-bearing in said strap, trans verse to the lens-plane, transverse arms se cured to said shaft and pads secured to the ends of said arms having universal joints for pressing the foot of saidpads evenly on their supports, substantially as specified.

- Y 3. In eyeglasses, the combination with a ro tatable shaft having opposed arms carrying pads at their outer ends, of. a folded strap forming a bearing for said shaft, transverse to the lens-plane and means for adjusting said strap in the lens-plane, substantially as specified. v

4. In eyeglasses, the combination with rotatable shafts having opposed arms carrying pads at their outer ends, said pads on loosejointed bearings, the axes of said shafts parallel to the lens-axes, of folded straps forming bearings for said shafts, means to vary the relative adjustment of said lens-axes and shaft-axes, substantially as specified.

5. In eyeglasses, the combination with eyeglass-posts, of folded straps forming shaftbearings at their folding-places, eyeglasssprings held by said-straps, means to secure said folded straps and eyeglass-springs t0- gether,and means to hold them,non-rotatably, by said securing mechanism, substantially as specified.
